. TELESCOPIC HORN.
SPECIFICATION forming part of Letters Patent No. 773,344, dated October 25, 1904.
Application filed May 24, 1904. Serial No. 209,516. (No model.)
' State of Pennsylvania, have invented certain new and useful Improvements in Telescopic Horns, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in telescopic horns, and has for its object the provision of novel means whereby horns may be telescoped and securely retained in the collapsed position.
The present invention relates to all forms of horns, such as are used for phonograph's, graphophones, musical instruments, and the like; and one of the many objects of my invention isto produce a horn that may be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly eflicient in its use.
My invention broadly consists in the novel construction. combination, and arrangement of parts to be hereinafter more specifically described, and fully pointed out in the claims.
In describing the invention in detail reference is had to the accompanyingdrawings, forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a vertical sectional view of my improved horn, showing the horn in the eX- tended position. Fig. 2 is a similar view showing the horn in the collapsed position. Fig. 8 is an enlarged detail view of the joint, show-- ing a vertical sectional view thereof. Fig. 4 is a similar view of the lid. Fig. 5 is atransverse sectional view taken on the line 5 5 of Fig. 1. Fig. 6 is a longitudinal sectional View of the funnel portion of the horn. Fig. 7 is a cross-sectional view of the funnel. Fig. 8 is a perspective view of one of the parts of the funnel, and Fig. 9 is an end view thereof.
In the drawings, the reference-numeral 1 represents the mouthpiece, 2 and 3 integral sections, and 4 the bell of the horn, these sections 1, 2, 3, and 4 being constructed in a manner as to permit the horn to readily telescope one section within the other. The section 3 carries at its enlarged end flanges 5 5, which are slightly curved, as shown at 6, to receive a lid or cover 7, which is adapted to form a locking engagement therewith, said lid carrying a handle 8. The sections 1 and 2 when in the collapsed position are inclosed within the section 3 and are held in this position by means of the lid or cover 9, carrying flanges 10, which are adapted to lock in the recesses 11, the latter being slightly curved, as shown in Figs. 1 and 2 of the drawings. The joint between the sections isformed by the curved depressed portion 12 and a similar raised portion 14L fitting therein.
The funnel-shaped portion 1 of the horn comprises a plurality of sections 15, a portion of their edges being curved, as indicated at 16 and 17, whereby each section may be secured one within the other, forming a funnel-shaped horn, and the rear end of these sections have their curved edges cut away,
as indicated at 18, whereby each section may 7 22 of the funnel-shaped portion of the horn.
In Fig. 7 I have illustrated how the different sections 15 are secured together by means of the curved edges 16 and 17, and while I have herein shown this construction of funnel for horns it is obvious that I may readily employ the'form of funnel illustrated in Fig. 1 of the drawings and that the convenience of handling the horn where it comprises a plurality of sections will be readily appreciated by those who have use for the same, and the many other advantages obtained by the use of this invention will 'be apparent from the foregoing description, taken in connection with the accompanying drawings.
It will be obvious that various slight changes may be made in the details of. construction without departing from the general spirit of my invention.
Having fully described my invention. what I claim as new, and desire to secure by Letters Patent, is
1. A horn composed of a plurality of telescopic sections, a lid on each end of the outermost of said telescopic sections to inclose the remaining section, substantially as described.
2. In a horn, the combination of a plurality of telescopic sections of gradually-increasing size, and a bell-mouth secured to the largest section, with two lids, one fitted to the smaller end of the largest section, the other titted to the larger end of the same section and within the bell-mouth.
3. A horn composed of a plurality of telescopic sections having curved grooves formed therein, and corresponding raised portions formed in the opposite sections adapted to extend into and lit said grooves, one of said sections composed of a plurality of sections, each last-mentioned section having its edges curved whereby said sections may be secured together, and means whereby said sections may be secured to the other sections, substantially as described.
In testimony whereof I allix my signature in the presence of two witnesses.
